A waterjet propulsion control system 10 comprises: an electric actuation system with at least one electric actuator 12 and 14; a motor controller system with at least one motor controller 16; at least one jet controller 18; a reverser 20; a fixed reverse scoop 22; a feedback system; a steering arm (30, Fig 3); and a power supply. The electric actuation system is driven by the motor controller system to power the steering arm and the reverser through operation of the at least one electric actuator. The feedback system is built into the electric actuation system as at least one encoder. The system may also allow a user to have direct actuator control and bypass the automatic settings for control system backup. A method of controlling a waterjet-powered watercraft that comprises a pair of electric actuators and associated motor controllers is also disclosed. In the method the electric actuators are connected to opposing ends of a steering arm but act in opposite directions to steer the watercraft. The use of electric actuators eliminates the need for the use of hydraulic actuators.
